PRESSER-FOOT FORYSEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 293,867, dated February 19, 1884,

' Application filed September 19,1883. (No modeLl To all whom it may concern.-

Be' it known that I, SAMUEL HALLIWELL, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Presser-Feet for Sewing-Machines; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be-a full, clear, and exact description of the same, and which said drawingsconstitute part of this specification, and represent, in- V Figure 1, a perspective view of the presserfoot socket with the foot attached;- Fig. 2, the

' socket with the foot detached; Fig. 3, the foot detached; Fig. 4, a vertical section of the socket through the transverse slot; Figs. 5, 6, and 7,

modifications. r i

This invention relates to an improvement in that class of presser-feet for sewing-machines inwhich'thefoot is constructed to be detached from the socket, so that'a plain foot may be used for common sewing, or attachmentsniade a part of the foot introduced, the object of the invention being an easy and ready adjustment of the foot to the socket, and whereby the proper position may be insured; and it consists in the construction of the presser-foot and itssocket, as more fully hereinafter described, and particularly recited in the claim.

In the best construction of my invention the presser-foot A is constructed with a shank,B, at its rear end, extending upward, and at or near its upper end a flange, a, is turned rear- 3 5 ward at substantially right angles to the shank B, as seen in Fig. 3. The socket O is constructed with a transverse slot, b, corresponding to the shank, and with a shoulder, d, formed therein corresponding to the flange a on the shank. The slot B opens at the lower -'end of the socket, and so that the shank of the presser-foot may be passed into the slot 1) from one side, the flange a passing onto the shoulder d, and when thus introduced a turn-but 5 ton, e, is arranged to be turned down over the equal the width ofthe shank, and so that the closed side of the slot forms a shoulder or bearing for the edge of the shank to locate it in its proper position transversely, as seen in Fig. 4. The socket is fitted for attachment to the presser-foot spindle in the usual manner.

Instead of the turn-button a set-screw may be introduced from the front or rear, as seen in Fig. 5. 1

Instead of making a transverse slot and shoulder in-the socket, as described, the socket may be constructed with a vertical recess in its face-say of dovetail shapeas seen in Fig. 6, and so as to leave a shoulder, 01, at the right position for the flange a on the shank, In this case the shank is constructed to correspond to the dovetail slot b, so as to be introduced from the upper end of the socket and drawn down until the flange a shall bear upon the shoulder d, as seen in Fig. 7. Then a setscrew through 'the shank may be introduced to clamp the presser-foot in position, as seen in Fig. 7. In either case the transverse shou1- der d and the flange a serve to locate the presser-foot in its proper horizontal plane, and the sides of the recess serve to locate the presser-foot transversely, and so that different attachments applied to their respective presserfeet may each be introduced into the socket and brought to their proper horizontal plane without, any special attention or care on the part of the operator.

-I claim- The herein-described presser-foot attach ment for sewingunachines, consisting of the presser-foot A, constructed with the shank B, extending upward therefrom, the said shank constructed with a, horizontal flange, a, com-f bined with the socket- O,'constructed with a recess corresponding to the shank, said recess provided with a vertical bearing or shoulder, and with a transverse shoulder,d, corresponding to the flange a on the shank, andadevice, substantially such as described, to secure the shank in said recess, all substantially as specified;

SAMUEL HALLIWELL.
